Characteristics of Tc-MEP Waveforms in Spine Surgery for Patients with Severe Obesity

Prospective multicenter study.The aim of this study was to evaluate transcranial motor evoked potential (Tc-MEP) waveform monitoring in spinal surgery for patients with severe obesity.Spine surgeries in obese patients are associated with increased morbidity and mortality. Intraoperative Tc-MEP monitoring can identify neurologic deterioration during surgery, but has not been examined for obese patients.The subjects were 3560 patients who...
